Import SuccessFactors Conection to SAC not pulling all records

Hi, I have SuccessFactors connected to SAC and I have noticed that not all records are being imported. At the moment any query I build only pulls around 15,000 records for events but in our system there are actually around 78,000.

Has anyone else experience this? Is there a specific table you need to start with or is this an issue with how the connection was set up?
